LDAP Client configuration

first, install required packages, in this article we will see how to configure LDAP client using CLI interface and GUI Interface

[root@ldapclient1 ~]# yum install -y openldap-clients nss-pam-ldapd sssd authconfig-gtk
[root@ldapclient1 ~]# yum install nfs-utils rpcbind autofs

Using GUI mode

install above packages then enter the command “system-config-authentication

ldap client

Using CLI mode

type command “authconfig-tui

Select [*] Use LDAP

select [*] Use LDAP Authentication

click Next

provide the ldap server details as shown above and click ok

verify the ldap user information using below command

[root@ldapclient1 ~]# getent passwd ldapuser1

as you see below there is no home directory for ldapuser1

[root@ldapclient1 ~]# su - ldapuser1
su: warning: cannot change directory to /home/ldapuser1: No such file or directory

Now mount user home directory using autofs

edit autofs master configuration file add entry

[root@ldapclient1 ~]# vim /etc/auto.master
# Sample auto.master file
# This is a 'master' automounter map and it has the following format:
# mount-point [map-type[,format]:]map [options]
# For details of the format look at auto.master(5).
/misc /etc/auto.misc
/home /etc/auto.ldapuser

now create /etc/auto.ldapuser file and add the entry for autofs mount

[root@ldapclient1 ~]# cat /etc/auto.ldapuser
* -rw

Now restart autofs service

[root@ldapclient1 ~]# systemctl restart autofs
[root@ldapclient1 ~]# systemctl enable autofs
ln -s '/usr/lib/systemd/system/autofs.service' '/etc/systemd/system/multi-user.target.wants/autofs.service'

login using ldapuser then verify you should get ldapuser home directory automatically

[root@ldapclient1 ~]# su - ldapuser1
Last login: Sun Mar 20 00:02:00 IST 2016 on pts/0
[ldapuser1@ldapclient1 ~]$
